the two parents, occurred on slopes above Sand Voe. (Confirmed 

 by Dr. F. B. White.) 



Salix herbacea L. — Dr. Buchanan White remarks on the 

 Shetland plant : — " The leaves seem a little more hairy than is 

 usual in our ordinary Scottish plant." 



Juniperus nana. — Dall of Lumbister, Yell. Bergs of Skel- 

 berry, Northmaven. A single fruit was found at the latter locality; 

 it was certainly that of very well-marked nana. 



* Potamogeton Wolfgangii Kihlm. ? Loch of Lumbister, 

 Yell. Mr. A. Bennett remarks that in looking at the various 

 forms assumed by P. heterophylluSy my plant comes nearest to the 

 above ; but that being only in flower, he cannot say that it is 

 identical. I believe that this form is at present definitely on record 

 from Finland only, but Mr. Bennett has little doubt that a speci- 

 men sent him by Dr. Neuman from Norbotten, Sweden, is the 

 same. Judging from my own collection, this form would appear 

 to be not uncommon in Scandinavia. I possess a type specimen 

 of P. Wolfgangii (P. salicifolius Holmen, non Wolfg.) which had 

 been named P. grammeus L., about a year ago, by Dr. Tiselius ; 

 thus the distribution of the plant can scarcely be yet known, its 

 recognition being so recent. I have not myself seen any British 

 examples, except those from Shetland, that I could refer to this form, 



(Phalaris canariensis, — Casual at Scalloway; and Lochend.) 



Avena pubescens L. — Ravine of the Estwick Burn, Olla- 

 berry ; a second locality. 



Nephrodium Oreopteris Desv. — By the mouth of the Grud 

 Burn, Roeness Voe. 



Several additional Hieracia, and a large series of Ranunculus 

 " acris," remain for a future report. 



ON SOME SCOTCH MOSSES OF THE GENCJS GRIMMIA. 

 By James Stirton, M.D., F.L.S. 



(The measuremetits subjomed are in 7nicro-millimetres, except where specified as in 

 millimetres.) 



IN the summer of 1866, I sent a few stems of a Grimmia (I had 

 no more), to the late Prof. Schimper of Strasburg, who, after 

 a considerable interval, replied that he could not identify the 

 moss with any species then known to him ; but that he could not 

 decide on raising it to specific distinction. He requested me at
